Contralateral ovulation shortens follicular phase length and favours pre-embryo development during ovarian stimulation with clomiphene citrate.
The present study was undertaken to evaluate whether the site of ovulation affects the following follicular phase length and pre-embryo development during infertility treatment with ovarian stimulation using clomiphene citrate. A total of 363 cycles in 97 patients undergoing infertility treatment (182 intrauterine insemination (IUI) cycles in 60 patients and 181 in-vitro fertilization (IVF) cyc...
متن کاملSelective expression of KrasG12D in granulosa cells of the mouse ovary causes defects in follicle development and ovulation.
Activation of the RAS family of small G-proteins is essential for follicle stimulating hormone-induced signaling events and the regulation of target genes in cultured granulosa cells. To analyze the functions of RAS protein in granulosa cells during ovarian follicular development in vivo, we generated conditional knock-in mouse models in which the granulosa cells express a constitutively active...
متن کاملHallmarks of Human Small Antral Follicle Development: Implications for Regulation of Ovarian Steroidogenesis and Selection of the Dominant Follicle
Regulation of human ovarian steroidogenesis differs from other species and precise knowledge on how human small antral follicles (hSAF) develop and acquire competence for continued growth and steroid output is still incomplete. The present study has characterized almost 1,000 normal hSAF collected in connection with cryopreservation of ovarian tissue for fertility preservation. The antral folli...
متن کاملSelection of the dominant follicle in cattle and horses.
The nature of selection of the dominant follicle is reviewed by comparing research results between cattle and horses. In both species, emergence of a follicular wave is stimulated by an FSH surge. The surge reaches a peak by the time the follicles attain 4 mm in diameter in cattle and 13 mm in mares. In cattle, all of the growing follicles >/=5 mm contribute to the decline in FSH concentrations...
متن کاملFollicle Online: an integrated database of follicle assembly, development and ovulation
Folliculogenesis is an important part of ovarian function as it provides the oocytes for female reproductive life. Characterizing genes/proteins involved in folliculogenesis is fundamental for understanding the mechanisms associated with this biological function and to cure the diseases associated with folliculogenesis. A large number of genes/proteins associated with folliculogenesis have been...
